<h2>Answer:</h2>

A chord divides a circle into two segments.

<h2>Step-by-step explanation:</h2>

<u>Chord--</u>

A chord is a line segment whose end point lie on the circumference of the circle.

<em> It divides the circle into two segments.</em>

If the chord passes through the center of a circle then the<em> chord is the diameter</em> of the circle and the two segments are of equal measure.

If it does not pass through the center of the circle then the two segments are of different measure.

The larger segment is known as a<em> major segment.</em>

and the smaller segment is known as a <em>minor segment.</em>

Answer:

segment whose endpoints are on a circle. Because its endpoints lie on the circle, any chord divides a circle into two semicircles. Any other chord divides a circle into a minor and major arc

The picture below shows the path that Puppy Liz is running. The electrical post is 40 feet tall. Puppy Liz usually starts at the

zimovet [89]

Answer:

Puppy Liz runs 34.61 ft.

Step-by-step explanation:

From the figure we can extract two triangles: one with angle 34° and adjacent 40ft, the other with angle 34°+23° and adjacent 40ft.

Let us call the distance from the pole to the fire hydrant $d_1$ , and the distance from the pole to the bench $d_2$ , then the distance $d$ from the fire hydrant to the bench is

$d=d_2-d_1$

which is the distance the Puppy Liz runs.

Now, from trigonometry we have

$tan(34^o)=\frac{d_1}{40}\\\\\therefore d_1= 40*tan(34^o)\\\\ \boxed{d_1=26.98ft}$

and

$tan(34^o+23^o)=\frac{d_2}{40}$

$d_2=40*tan(34^o+23^o)\\\\\boxed{d_2=61.59}$

Therefore, the distance $d$ Puppy Liz runs is

$d=d_2-d_1$

$d=61.59ft-26.98ft\\\\\boxed{d=34.61ft}$

What is the center and radius?<br><br> X^2+y^2+6x-6y=-14

Zolol [24]

Answer:

Therefore,

$Center\ is\ C(-3,3)\\and\\Radius= 2\ units$

Step-by-step explanation:

Given:

A Equation of a Circle that is

$x^{2} +y^{2}+ 6x-6y=-14$

Which can be written as

$x^{2} +y^{2}+ 6x-6y+14=0$

To Find:

Center C( -g , -f ) = ?

radius = r =?

Solution:

General Equation of a Circle is given as

$x^{2} +y^{2}+ 2gx+2fy+c=0$

On Comparing the Given equation with the General equation we get the following values,

$2g=6\ and\ 2f=-6\ and\ c=14\\\therefore g=\frac{6}{2}=3\\ \\\therefore f=\frac{-6}{2}=-3\\$

Now, Center and Radius for above circle is given as

$C(-g,-f)=(-3,-(-3))=(-3,3)\\and\\radius = r=\sqrt{(g^{2}+f^{2}-c )} = \sqrt{(3^{2}+(-3)^{2}-14)}\\\\\therefore radius = r=\sqrt{(18-14)} \\\\\therefore radius = r=\sqrt{4}=2\ unit\\$

Therefore,

$Center\ is\ C(-3,3)\\and\\Radius= 2\ units$
